History outside of the Bible has confirmed Saul, David, Solomon etc. to be real kings of Hebrews. While history states origins of the Hebrews is not known with any certainty, third party writings bear record to their existence as early as biblical records suggest.

History, which derives its records from evidence, is science.

For the historical evidence, see

It is not helpful for Christianity for some Christians to label as myths what science already claims are facts.

Is citing of Hebrews in external records as early as the Bible suggests not more important than history’s inability to confirm the crossing of the red sea? But then again, is science amenable to proving of a temporal parting of a sea, or does evidence reside in the faith we repose in a God who cannot lie to us yet be considered loving and kind? Is faith not the only possibility for veracity of temporal parting of a red sea?
